Figure 3-1 shows the SX-100 cabinet which incorporates the
4 . 0 1
equipment shelf, maintenance panel and primary power supply
mounted from the front of the cabinet.
4.02 Figure 4-l shows the SX-200 cabinet which incorporates two
equipment shelves, the maintenance panel, the optional reserve
power supply mounted in the base of the cabinet and the primary
power supply mounted on the lower rear door.
4.03 These units are described in more detail in the following para-
graphs.

4.04 The equipment shelves contain the PCB cards in the necessary
quantities required for a particular configuration, as illustrated
in Figure 4-2. Shelf 1 must always be included as it contains all the
necessary control circuitry. Shelf 2 is included on the SX-200 system
when the number of line, trunk and receiver cards exceeds 15.
4.05 Equipment Shelf 7 contains the four common control cards plus
the required number of line, trunk and receiver cards. The com-
mon control cards are color-coded and held in card positions 18
through 20. The console control cards occupy positions 16 and 17; the
first receiver card is held in position 15. These card positions are fixed
for systems. Card positions 1 through 14 may be equipped with line,
a ll
trunk or receiver cards as shown in Figure 4-2. If there is a require-
ment for the PBX to be accessed from a MITEL RMAT System (see
Section MITL9105/911
tion and Test System), the second Console Control card is replaced by
a Remote Control - PABX card (see Figure 4-2).
4.06 Equipment Shelf 2 (SX-200) is identical in construction to Shelf
1, and provides for 12 additional card positions which may
house line and/or trunk cards as required. Card positions 13 through
22 are not used. Access to Shelf 2 is made through the shelf intercon-
nect cables plugged into the rear of each shelf.
4.07 A brief description of each card type is given below:
Standard Line Card
Provides eight circuits which serve as interfaces between the
station equipment and the switching circuitry.
The SUPERSETTM sets may not be used with this line card.
